   Senior Fullstack Developer

   Microniq Business Automation AB

   As part of a team, I work on developing a resource planning system that helps cleaning companies run more efficiently and simplifies their workflows. We tackle both the frontend and backend to create a solution that’s both reliable and easy to use. The frontend is built with React and Material UI, offering a clean, user-friendly interface, and we use Auth0 to make sure authentication is secure and simple.
   
   On the backend, we’ve put together a solid system using a PostgreSQL database and a REST API built with Express.js. We’ve also integrated the Fortnox.se API to automatically sync financial data with internal records. Real-time updates through WebSockets ensure users always have the latest information at their fingertips. The whole solution is deployed on Google Cloud Platform and are running as containers on Cloud Run.
   
   The system cuts down on manual work and helps businesses save time while staying productive and cost-efficient.

3. May 2021 - January 2026 Employment

   Senior .NET System Developer

   Trygg-Hansa

   At Trygg-Hansa, I worked as a .NET System Developer and was in charge of improving and maintaining REST APIs in C# .NET. These APIs supported over 50 different insurance claims workflows. Each workflow was part of a flexible system that used JSON definitions, and our backend would read these definitions and provide the right data and actions to the frontend.
   
   My main tasks were:
   - Building and updating the backend logic for claims, making sure data was collected from and saved to a large, complicated MSSQL database with more than 100 linked tables.
   - Being the go-to person in the team for the MSSQL database, figuring out how the tables were connected, tracing where data came from, and deciding the best ways to store and fetch the claim information you see on tryggghansa.se.
   - Developing and improving the REST APIs that run "Mina sidor." This included lots of features for customers, like chat, secure messaging, choosing a workshop (with special logic for finding options based on postcode), and digital power-of-attorney. For the last feature, I created a new REST API from scratch, and added support for BankID signing.
   - Working closely with my team in agile Scrum sprints, taking part in code reviews, planning, security checks, and collaborating with other teams
   
   In all of this, I focused on writing clear, easy-to-maintain code, building strong integrations, and getting features out that really made a difference for our customers and the business.
